Each cylinder head has a plastic cover for the ignition coil cabling and top of the cylinder
head. The covers “push fit” into rubber grommets on the cylinder head covers.
A sound absorption cover for the top of the
engine also covers the two Valvetronic motors.
This cover is fixed to the intake manifold hous-
ing using four bolts.
The cylinder head covers are made from plastic. The retaining sleeves for the ignition coils
have molded-on gaskets. The sleeves must be replaced if any hardening or damage is vis-
ible on the gaskets. The sleeves are inserted into the cylinder head through the cylinder
head cover (nos. 1through 4).

Flywheel
The lightweight flywheel is made from a laminated plate. The
starter ring gear is also the increment wheel for engine speed
and crankshaft positioning/misfire detection.
The ring gear is riveted directly to the flexplate (6). The fly-
wheel diameter is 320 mm.
Vibration Damper
The vibration damper is a torsional vibration absorber (axial
design). The outer edge of the damper has a notch (1) to
accept the locating tool when positioning the crankshaft for
initial setting.
The locating tool inserts into the raised mount in the front
cover (2). R Re
